Hi
 
New to the group and hope you can help with a query?
 
I've been asked to create a report that uses multiple parameters, but not all of them will be selected when running the report, so need to know how I code the select statement to allow for blank entries if not required?
 
Thanks

Not certain exactly what you want as there isn't really enough information, however I'll assume you have a SQL command you wish to pass parameters too to filter records.
 
For examples sake we'll say you've got an optional country parameter, if left blank you want to return all countries otherwise return the country selected.
 
First create the {?country} parameter, set the default value as a single space (or whatever else you'd like to use).
 
To incorporate this in to your query it would look something like this;
 
select *
 
from countries
 
where
countries.name = case when {?country} = " " then countries.name else {?country} end
 
Very simple example but hopefully you get the idea.
 
Regards,
Ryan.

2008 allows for no param to be entered.
you can use the
hasvalue(?param)
not(hasvalue(?param))
to define how the select expert should act.
here is an example

Good morning
Have had a look at the help some of you gave yesterday, but still a bit stuck.  Here is a bit more detail on my query.
From the Report Fields listed below, the report requestor would like to have the function of selecting 1 field and not having to select anything else, or multiple fields and again leave those not required blank.
Here's what I've got so far:
 
{?Template} ="" and
{?PTL Number} = "" and
{?Requestor Name} = "" and
{?CI Name} ="" and
{?Impact} ="" and
{?Status} ="" and
{?Source} ="" and
{?Completion Code} ="" and
{?Opened By (Group)} = "" and
{?Closed By (Group)} = "" and
{?Service Name} = "" and
{?Closed By (PTL)} ="" and
{?Opened By (PTL)} ="" and
{Incident.Full Name Assigned To} ={@FullName 2} and
{Incident.Open Date & Time}>={?FromDate} and
{Incident.Open Date & Time}<={?ToDate} and
{Incident.Status Description:} in ["Accepted", "Assigned", "Change Pending", "Closed", "ClosedMail", "Completed", "In Progress", "Waiting For Customer", "Waiting for..."] and
{Incident.Group Name} = {?Group}
 
Any help would be much appreciated.
 
Thanks

I have not used 2008 yet so I am not exactly sure on the syntax.
 
maybe...
((not(hasvalue({?Template}))) or {?Template}={table.templatefield})
and
((not(hasvalue({?PTL Number}))) or {?PTL Number}={table.PTLfield})
and
((not(hasvalue({?Requestor Name}))) or {?Requestor Name}={table.requestorfield})
and
...
